In the particular form of the invention as shown in these drawings, 20 represents a window casement or frame having sides or stiles 21, trim 22, and stool or sill 23. The lower sash 24 and the upper sash 25 slide in the frame and are provided with any suitable balance or supporting means. In the arrangement shown, the lower sash is balanced by spring counter-balances 26 having the usual metallic bands or ribbons 27. The lower ends of these bands are secured to channel shaped supports or bearings 28, as shown particularly in Figure 13. These bearings run in channels or guideways 29 in the sides of the frame, as shown in Figures 2 and 4. The Y inner faces of the bearings 28 have holes or open ings 30 preferably of rectangular form with inwardly sloping or beveled bottom'edges 31. The sides of the bottom sash 24 are provided at the lower corners with plates '32 having trunnions or pivots 33 which project through the holes 30 in the bearings 28. These pins have laterally extending projections 34 which coact with the channel shaped bearings or supports 28 to lock the parts together while permitting the swinging of the sash. It will be noted that the beveled lower edge 31 is drawn by the spring balance against the lower side of the pin or pivot 33 and the purpose of the beveling performs an important function which will be presently described. Plates 35 each having inwardly projecting lugs 36 are secured in the channels 29 at a short distance above the bottom of the frame. The projections 36 extend inwardly a sufficient distance so that they are embraced at times by the U- shaped bearings 28, as shown in Figure 4. The pivots 33 will normally pass between the stops 36 but when the sash is tipped, the pivots with their projections 34 will rest againstthe lower edges of these stops, as shown in Figure 5.

The lower sash moves vertically in guideways and is held in place by stop rails or strips 37. Sections of these rails, as shown at 38, are hinged at 39 to the frame and arranged to swing inwardly, as shown in Figure 2. In the present instance, short sections of the stops or strips are left below the hinged portions to provide clearance for the handles 40 on the lower sash when the lower sash is swung inwardly as shown in Figure 2. The stops or strips 38 are provided with fastening screws 41 which pass through the stops and engage with fixed threaded discs or nuts 42 on the inner faces of the side members of the frame, these'screws' and nuts providing means for fastening the hinged stops in closed or normal position.

When the lower sash is to be swung inwardly as for cleaning, the fastening members 41 are disengaged and the strips 38 swung inwardly to provide clearance for the sash. The sash is then raised until the lower edge passes above the short strip sections at which time'there is nothing to hold the lower edge from moving inwardly. As soon as the sash reaches this position, the lower edge slides on the pivots 33 down'the slanting edges 31 until the pivots strike against the inner edges of the holes at which time the pivots 33 will have moved over a sufficient distance to engage with the inner projections 36 on the plates and thereby prevent the upward movement of the sash. The sash is then swung or tipped inwardly as shown in Figure 2 until it restsupon the shortstrips which hold it in substantially horizontal position. At this time the flat faces of the pivots 33 and projections 34 will engage with the lower edges of the projections or catches '36 so that the window is held securely in such adjusted position. If the sash is provided with recessed handles, the short stop strips below the hinged sectionsmay be omitted and the window will then rest on the sill'23, the plates 35 with their lugs or projections 36 being moved down wardly a corresponding distance.

The upper sash 25 is also arranged so that it may be swung inwardly so that it will lie over the lower sash, as shown in Figures 2 and 5. The upper sash is also provided with balances, preferably of the spring type, having metallic bands or ribbons 43 which are secured to U-shaped bearings 44, as shown in-Figure 16, which are similar to the bearings 28 and which have holes 45 with sloping bottom edges 46, which holes are preferably somewhat narrower than the holes 30 as comparatively slight lateral movement of the upper sash will be sufficient to prevent the sash from being unintentionally drawn up while it is being swung inwardly. 7

The top sash is narrower than the bottom sash and slides in channels or guideways 47which are formed in part by means of auxiliary stile strips or pieces 48 which are secured to the main stiles 21 in any suitable manner as by means of screws 49. The frame is provided with parting strips 50 forming parts of the channels for the top sash, these parting strips terminating at approximately the bottom edge of the top sash in order to permit the-sash to swing inwardly. The top sash is provided with plates or brackets 51,

Figure 1'7, having pivots 52 with projections 53 in the stile'pieces 48, as shown in Figure 4. Plates -55 withlu'gs or projections 56are arranged in the grooves 54 near the bottom of the frame, "as shown in Figure'2, and co-operate with the pivots 52 and projections 53 when the sash is to be swung inwardly.

It will be seen that when the top sash is moved downwardly so that it is no longer guided by the parting strips 50, the lower edge of the sash will slide inwardly due to the pivots sliding laterally on the sloping or beveled edges 46 of the bearings 44 so that after the pivots have passed below the lugs 56, they will tend to catch on the'lower edges of the inner lugs as soon as the top of the window is tipped to any appreciable degree, but the upper and lower surfaces of the projections 53 may be slightly curved or beveled,

as shown, to permit the same to pass between the lugs 56 in the normal operation of the window. When the top sash is to be swung inwardly, it is slid downwardly until the upper edge is free to pass under the parting strips and the upper edge is then swung inwardly beyond the parting strips and the sash raised until the projections 53 engage with the lugs or catches 56 and then the sash may be swung down to horizontal position where it will rest upon the bottom sash, as shownin Figure 2. Any suitable means (not shown) maybe provided if desired for holding either the top or bottom sash in partly adjusted position to provide for ventilation or the like.

The weather stripping or means for making the window tight also forms an important feature of this invention. A plate 57 is rabbeted or set into the lower sill member and is provided with an upwardly extending tongue or flange 58 which is recessed on the'outer side to provide a shoulder 59, as shown in Figures 5 and 12. A grooved or substantially U-shaped weather strip 66 is secured to the lower edge of the bottom sash 24 and engages with the flange 58 to make a tongue and groove closure. The outer portion of this strip is of approximately the same thickness as the ofiset in the tongue 58 so that it abuts against the shoulder 59 and makes a substantially flush outer surface.

The sides of the lower sash 24 are provided with saw cuts or kerfs 61 for receiving the legs 62 of angle weather strips 63 which fit freely or slidably therein. The upper ends of these legs have slots 64 through which pass screws 65 for fastening the strips in position although allowing movement thereof. The other legs 66 of the weather strips 63 engage with U-shaped weather strips or channels 67 which are secured in grooves in the stile members'48, as shown in Figures 3 and 4. The lower ends of the legs 62 areslotted or cutaway as shown at 68 to provide clearance when the sash is swung to horizontal position.

It will be noted that the lower portion of the leg 62 will always be in engagement with the lower end of the channel 6'7 so that these parts will always properlyopen and close, somewhat in the nature of a jack-knife blade, when the window is swung. It will also be noted that on account of the free or slidable engagement of the legs 62 with the sides of the sash they will be selfadjusting regardless of any swelling or shrinkage of the sash. By means of this arrangement a very tight closure is always provided between the sides of the lower sash and the frame.

The ends of the tongue 58 abut against the grooved strips 67- at the corners of the window so that these portions are also fully protected against air passing therethrough.

The arrangement of the top sash in its guideways is such that it may be readily made tight by means of more or less common arrangement of weather stripping. The sides of the sash are provided with groves 69 which are adapted to receive channel shaped or U-shaped weather strips 70, which strips are secured to the sides of the frame as shown in Figure 3. The upper edge of the top sash is also grooved as shown at '71 for engagement with a horizontal weather strip '72, as shown in Figure 2.

From this description it will be seen that I provide a double sash window that may be completely washed from the inside of the room and without the necessity of removing screens, awnings or the like, on the outside of the window. Furthermore, the complete window is weather stripped by tongue and groove metal weather stripping which will make it substantially weather proof throughout. While I have described a preferred form of my invention, it will also be noted that changes may be made in the details of construction or arrangement of parts to adapt the same for different styles or types of windows or for different conditions and therefore I do not wish to be limited to the particular construction described except as set forth in the following claims, in which I claim.

1. A window of the character set forth, having a vertically slidable sash, means for balancing the sash, pivotal connections between the lower portions of the sash and the balancing means, adjustable guides for guiding the sash in its vertical movement and catches for preventing the upward movement of the sash which are normally inoperative but which become operative when said guides are adjusted out of operative position.

2. A window having a sliding sash, balances arranged at either side of the sash, pivotal connections between the sash and the balances arranged to permit the inward movement of the pivots at predetermined times, movable guide stops for the sash, and projections arranged within the window frame adapted to be engaged at times by the pivot members, the arrangement being such that the pivot members will normally pass said projections but when the guide stops are moved out of operative position, will automatically move into position to engage said projections.

3. The combination of a frame, a sash slidably mounted in said frame, balances having flexible members for supporting the sash, bearings secured to said flexible members and having holes with inwardly slanting lower edges, pivot members secured to the lower corners of the sash and projecting through said holes and adapted to slide on said edges, stop lugs secured to the frame and normally out of alinement with said pivot members, and movable rails for guiding the sash in its vertical movement, the arrangement being such that when the rails are moved out of engaging position the lower edge of the sash will slide inwardly bringing the pivot members in position to engage with the lugs, thereby preventing the upward movement of the sash when it is swung inwardly.

4.. A device as per claim 3 in which the pivot members are provided with heads or projections for engagement with the stop lugs.

5. In a window, the combination of a sash, pivots secured to the sides of the sash and having lateral projections, U-shaped bearings having holes with inwardly sloping lower edges engaging with the pivots, flexible balance members for supporting said bearings, a frame having vertical guideways for said sash which are formed in part by hinged rails adapted to be swung out of position to permit the tipping of the sash and stop members arranged adjacent to the lower portion of the frame which are adapted to be engaged by the pivot members when said rails are swung out of engaging position.

6. A bearing or support for windows comprising a channel shaped member having an opening in the face thereof with a downwardly sloping supporting edge.

7. A pivot for supporting a window sash com prising a rectangular bearing section with a lateral projection at the end thereof, the upper and lower edges of said projection being curved or tapered, substantially as described.

8. A double hung sliding window having balances for the top and bottom sash and having sliding pivotal connections between the balance members and the respective sashes and catches arranged on the frame which are normally out of the path of movement of said pivots but which are adapted to be engaged thereby when the sash are permitted to slide on said pivotal connections.

9. A double hung sliding window having its sashes pivoted to flexible balance members and having automatic locking means for holding the sashes in position to be swung inwardly, substantially as described.

10. In a window, the combination of a frame, a sash pivotally mounted in said frame and having longitudinal slots in the sides thereof, angle weather strips each having one leg engaging with the respective slots and recesses in the frame for receiving the opposite legs of said strips.

11. In a window, the combination of a frame, a

sash pivotally mounted in the frame and having slots in the sides thereof, angle weather strips each having one portion fitting freely in the slots on the respective sides of the frame, means for holding the upper ends of the strips in engagement with the respective slots while permitting limited lateral movement thereof, and slotted weather strips secured in the frame and adapted to coact with said angle strips.

12. In a window, the combination of a frame, a sash pivotally mounted in the frame, metallic angle strips each having one branch engaging with a slot in the respective sides of the frame and having transverse slots adjacent to the top thereof, screws engaging with said slots, and U-shaped strips secured in the frame and embracing the other branches of said angle strips, said angle strips also having slots at the bottom thereof to permit the swinging movement of the sash with respect to the frame.
